My partner is an inmate at Miller County Jail

i have searched and searched for a web page/ site where i could go and find my partners name on an inmate list, i must be doing something wrong as i am unable to find one for that jail, he had been held in Mobile County Jail , Alabama, there i was able to find an inmate list and could track him when he was transferred up to Texarkana.. please is there any chance that anyone might know of somewhere i could go to try and find him ? I have tried the Arkansas Department of Correction web site but it says it is unable to find a match, i know he is there as i write to him evey week and he calls me collect from there.He was sentenced on the 27th October but has been in there since the 23rd April.
